Aiden is shaped around the keyhole bridge that first appeared on frames of the 1930s and was refined into this gentler arch in the decades that followed. A deeper lens brings the proportions into the present, while twin pin rivets at the front keep it rooted in midcentury craft. Offered in five colorways, it is the rare frame that feels equally considered at the office, at dinner, and everywhere between.
